A new study published in the journal Optometry & Vision Science examined the a large population of pre-school children and tested their depth perception using the Stereo Smile II test. The researchers then looked at the association of poor 3D vision with vision disorders.
The study found that children with vision disorders had significantly worse median stereoacuity than that of children without vision disorders. Children with the most severe vision disorders had worse stereoacuity than that of children with milder disorders.
The researchers also found that testability was excellent at all ages of the children included in the study. The results support the validity of the Stereo Smile II for assessing random-dot stereoacuity in preschool children. The results also point to the need to take children who have poor stereo vision to a developmental optometrist to be evaluated and treated for developmental vision disorders that may be the cause of the poor stereo vision.
